I have the same issues with Mac running the latest El Capitan and Safari-- and have tried all three others browsers, as well. It worked fine last week and the mobile app works fine right now, so I know my internet connection is fine.

Experiencing same issue on Mac OS 10.11.6 with various compatible browsers.

Have just called Slingbox support by phone and they are so clueless they didn't know of the problem until I told them to check out the community online. They then said they would escalate the issue. It's like nobody knew at 10am ET this day.

Yes it does but for goodness sake get rid of the SlingPlayer logo in the top left...this is a designated area for sports clocks, scorelines and station identification...WE KNOW WE AS CUSTOMERS ARE USING the Sling player !!!

Same issue as the others here. With the usual link, Windows 7 w/Chrome 64-bit, doesn't work, neither does IE, although they worked just fine up until today. The alternative link provided here works though. Thanks, hope to see the standard link fixed soon.

With all due respect, your company has done a lousy job today or communicating with customers about this issue, both online and on the phone. Your phone support people are clueless and were not even aware of the problem until people started calling them early this morning.

Since then, except for your message on this forum, there has been no acknowledgment, no confirmation, no detailed explanation of the severity of the problem and what you are doing to fix it.

Get on the stick, acknowledge the issues, admit openly that right now there is nothing users in the field can do to fix the issue, and give a timeline to fixing what is obviously a problem you do not have a firm handle on.

i have two slingboxes on two differnt Tivos. when i go on this link it shows both but when i click on either, i get the same slingbox (slingbox 1) if i click on slingbox 2 i also get slingbox 1 ... when will the regular service be back up???

Having same problem and prior to reading this post, reset Slingbox 350 using the reset button on back and now I am prompted to setup the Slingbox on PC or mac using web browser. Problem is, that I cannot do that either. Have tried Slingbox Player and am able to the see the 350 on my list, however, when I try to set up, it trys connecting for while then returns: Unable to connect to Slingbox. Please check that your box is on and connected to network.

I have the exact same problem. I have 2 x Pro HD boxes which I was able to watch yesterday - but not today on either my HTP or my laptop. I have downloaded from the support download section an old client version so able to watch the slingboxes - but the quality is very poor. Both my HTPC and Laptop are up to date running Win10?

There is clearly some incompatibility following recent windows update.

This is most definitely to do with Windows 10. I manually update my Win10 laptop. I was watching my Sling 350 about 2 hours ago. I shut it off and then did a windows update. Well, got the latest Win10 updates which installed fine. Rebooted. Then went back to use my 350 and now getting the same message about incompatibility. Also, the link SlingSupportHidy gave is not working for me. It's denying my login info which I know is right. I even changed my p/w via the Sling site and still no luck. Slingbox, fix this.

Still getting this.......'We're sorry, but your web browser, operating system, or the combination of both is not currently supported by the SlingPlayer plug-in. Please click here for more information.'.

same issue...Toshiba Satellite running Win 10 Home and IE 11.589.10586.0. tried Edge with no luck, tried chrome with no luck. works fine on Dell Inspiron with Win 10 Home and IE 11.54510586.0...alos works fine on ipad...WTF!

I don't believe from what I'm reading and hearing that the problem has anything to do with end user software or configuration. This appears to be a hosting issue with Slingbox because there were no software changes for users in the last 24 hours and this problem started overnight Sunday into Monday.

Your guess is as good as mine, but again, I do think this is a problem on their end and they know it despite not wanting to communicate very well with their users. Hang in there and try the alternative mentioned above by a support person to view your Slingbox...

We're now going on 24-plus hours of the service down with little acknowledgement or updates from Slingbox. This is simply just poor communications and shows a total lack of people talking inside the company. I'm extremely disappointed in Slingbox right now.

I'm a longtime Slingbox user and this outage shows that the switch to a browser-based system was a mistake from the beginning all for the ability to sell ads and Slingbox make additional revenue.

Stopped working for me on Windows 10 all browsers. Message says We're sorry, but your web browser, operating system, or the combination of both is not currently supported by the SlingPlayer plug-in. Please click here for more information.

i am getting the same error, the backup worked for me on safari. I paid a lot of money for my sling box an until now have never had a problem with it. I expect this issue to be resolved or all the recommendations i give to people will be no more

Mine doesn't give me the message this morning, but I am still out of luck. I don't know how to change the name of my cable box, since I've changed cable boxes. I don't get the video....only audio. Anyone know how to change the choice of cable boxes? Thanks
